Hello: I fear the worst. While brushhogging with my '52 TO30, it began to run a little rough and feel a little tired, and it was running a bit hot. No big deal I thought, probably just needs a tuneup. Then the oil pressure, which usually shows low anyway, dropped to almost nothing, and the valves started hammering big time. I probably should have shut it down right there, but I wanted to get out of the field with it and back to where I could take a good look at it. When I got back over to the garage, as soon as I throttled down, it just shut off. Tried to start it back up, and it wouldn't crank. Just clunked. I hoped that maybe the battery hadn't been taking a charge, as it's quite old, so I tried jumping it. Still wouldn't turn over. Tried turning the crank by hand by putting tension on the fan belt and turning the fan, but I couldn't budge it. While I was looking things over, I noticed that there was oil dripping out of the clutch/flywheel housing, which I'm pretty sure shouldn't be happening. After it sat for a good long time, I tried the starter again. This time, it turned just a little bit. So now I'm thinking, maybe it just IS the battery. So how about some ideas? Does it sound like the engine siezed up? Does a siezed engine ever UN-seize, and would the starter be able to turn it at all? What about the oil dripping from the clutch housing - rear seal gone? Is there any hope for this engine? Thanks all.

An engine can reach high heat and sieze and then loosen after a cool down period. The easiest way is to look at the oil. Pull tour dip stick and look at the oil. If it appears shinny, you have spun your rod or main bearings. If the oil is a light brown you have waterin your oil, and have a bad head or head gasket. If niether are true try putting oil in the spark plug holes and let it set fot a day or so and try to turn it over. If she does free-up she will probably run a little ruff. There is a reason for the lock up make sure you check everything before you run her.

Do you have any water in the oil, or oil in the coolant?

Phil:
I don't think so. As far as I can tell, the oil is all oil, and the coolant is all coolant.

it sounds like you got a big bill comeing.it sound like you spun the bearings on the crank shaft. best way to tell is drop the oil pan and if you find brass in the pan the bearings are gone!!p.s. after they seize thay will lossen up but will stop again soon check in the pan before you run any more good luck
